Key electrical and mechanical differences between the two devices
| Parameter | AD8602DRZ | AD8602DR-REEL7 | Why it matters |
|---|---|---|---|
| Amplifier Type | CMOS, Rail-to-Rail Input/Output | CMOS, Rail-to-Rail Input/Output | Defines the core topology and input/output swing capability; identical type means the same signal-handling behavior. |
| Number of Channels | 2 | 2 | Channel count must match for pinout and circuit topology compatibility. |
| Gain Bandwidth Product | 8.4 MHz | 8.4 MHz | Determines the maximum usable frequency for a given closed-loop gain; matching GBW ensures equivalent AC performance. |
| Input Offset Voltage (max) | 500 µV | 500 µV | Affects DC accuracy; identical offset spec means comparable precision in signal conditioning. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Must match the system supply; identical range allows drop-in use in the same rail configuration. |
| Supply Current per Amplifier | 750 µA | 750 µA | Impacts power budget; matching quiescent current preserves thermal and battery-life characteristics. |
| Input Bias Current | 1 pA (typ) | 1 pA (typ) | Low bias current is critical for high-impedance sensor interfaces; identical value ensures equivalent loading. |
| Package / Mounting | 8-SOIC, Surface Mount | 8-SOIC, Surface Mount | Package and footprint must match for PCB layout compatibility and drop-in replacement. |
| Packaging / Ordering Format | Tube | Tape & Reel (7-inch) | Affects assembly line handling and inventory; reel packaging suits automated pick-and-place, tube suits low-volume or manual assembly. |

Frequently asked questions
What are the AD8602DRZ and AD8602DR-REEL7?
Both are dual, precision, low-noise, CMOS operational amplifiers from Analog Devices. The AD8602DRZ is supplied in a 8-lead SOIC package in tube form, while the AD8602DR-REEL7 is the same device in the same 8-lead SOIC package supplied on a 7-inch tape-and-reel for automated assembly.
Are the AD8602DRZ and AD8602DR-REEL7 electrically identical?
Yes. Both part numbers refer to the same AD8602 silicon die in the same 8-lead SOIC (R-8) package. The only documented difference is the packaging and shipping format: tube (DRZ) versus 7-inch tape-and-reel (DR-REEL7).
Can the AD8602DRZ and AD8602DR-REEL7 be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable, since both are the AD8602 in the 8-lead SOIC package. The choice between them is driven by manufacturing requirements (tube vs. tape-and-reel) rather than by device performance.
What are the key specifications of the AD8602?
The AD8602 is a dual CMOS op amp with low offset voltage (typically 80 µV, 500 µV max), low input bias current (typically 1 pA), low noise (about 8 nV/√Hz at 1 kHz), and a unity-gain bandwidth of approximately 8 MHz. It operates from a single supply of 2.7 V to 5.5 V and is specified over the −40 °C to +125 °C temperature range.
What is the difference between the DRZ and DR-REEL7 suffixes?
The "DRZ" suffix denotes the 8-lead SOIC package in tube form, with the "Z" indicating RoHS-compliant lead-free construction. The "DR-REEL7" suffix denotes the same 8-lead SOIC package supplied on a 7-inch tape-and-reel. Both are RoHS-compliant.
Which part number should be ordered for high-volume automated assembly?
The AD8602DR-REEL7 is the appropriate choice for automated pick-and-place assembly, as it is supplied on 7-inch tape-and-reel. The AD8602DRZ in tube form is typically used for prototyping, low-volume, or manual assembly.
Do both parts share the same pinout and PCB land pattern?
Yes. Both are the AD8602 in the 8-lead SOIC (R-8) package, so they share the same pinout and PCB land pattern. No layout change is required when switching between the two part numbers.
Are both the AD8602DRZ and AD8602DR-REEL7 RoHS compliant?
Yes. Both part numbers are RoHS-compliant. The "Z" in AD8602DRZ explicitly denotes lead-free, RoHS-compliant construction, and the AD8602DR-REEL7 is likewise supplied as a RoHS-compliant device.
